INK BOTTLE Filed Jan. 19, 1955 :NvENToR Pg/U5 M, @UT/ ER 0.134%' Wm A Patented July 21, 1936 i UNITED STATES PATENT oFFlcE i INK BOTTLE Fabius Mj. Butler, Seattle, Wash. Application 'January 19, 1035, serial No. 2,561 1 claim. (c1. 1z0-t9) the sides and over the end, due to its projection into4 the. bottle. If the bottle contains little ink, then the point is notproperly covered to insure iilling by suction.

To overcome this disadvantage, certain improvements have heretofore been made, such for instance as the patent to H. Smith, No. 1,308,817 Aof July 8, 1919, wherein an insert is applied t0 the bottle and this isequipped with a cuphaving a valved base opening through which the cup will be filled on inverting the bottle, but which will automatically close when the bottle is turned to upright position, thereby to trap sufficient ink for lling a pen therefrom. While the device of Smith is satisfactory to a certain extent, it is relatively expensive and occupies a considerable amount of space in the bottle.

Another form of device is shown in U. S. patent to C. W. Dennis, et al. No. 1,966,754 of July 17, 1934, consisting of a cup member inserted within the neck portion of the bottle, which principle is much like that of Smith, above referred to, and having the undesirable feature of being an extra inserted element of a comparatively expensive nature and not entirely satisfactory from the standpoint of ink holding.

In view-of the undesirable features of bottles of this type heretofore employed, it has been the principal object of this invention, to provide an improved form of bottle wherein the neck portion provides a pen filling cup and this is connected to the bottle by means of a restricted neck portion forming a seat for a valve member of novel form which operates automatically to admit ink to the cup when the bottle is inverted and will seat and retain the ink in the cup when it is turned to upright position.

It is also an object of the invention to provide a novel form of valve member which operates vnot only as the valve but is so shaped as to serve, as a rest for the pen in filling and also as an air trap when the bottle is inverted for filling the cup.

Another object of the invention is to provide a construction that isless expensive than those previously used, by reason of converting the bottle neck portion into a filling cup as distinguished from the use of inserted elements `for the purpose.

Other objects of the invention reside inthe details of construction of the various parts, in their relationship and mode of operation as will hereinafter be described.

In accomplishing these and other objects of the invention, I have provided the improved details of construction, the preferred forms ofI which are illustrated in the accompanying drawing, wherein l v Fig. l is a cross sectional view of an ink bottle constructed` in accordance with the present invention, in normal position.

Fig. 2 is a view in cross section illustrating the filling of the neck portion with ink by inversion of the bottle.

Fig. 3 is a cross sectional view illustrating the filling of a pen with ink trapped in the cup incident to turning the bottle to upright position after being inverted as in Fig. 2.

Fig. 4 is a sectional detail of an alternative form of construction.

Referring more in detail to the drawing- I designates in its entirety, an ink bottle which may be of any suitable or convenient size for a.

substantial supply of ink and provided at the top with an extended, integral neck portion 2 over which a cap 3 is removably threaded. The neck portion, in this particular instance forms the pen filling cup 4 and this communicates with the interior of the bottle proper through a neck passage 5 of a restricted diameter. The base or bottom of the cup 4 is conically tapered downwardly to the central passage 5 and preferably would have a smoothly ground surface to provide for accurately seating a valve member that is applied thereto.

The valve member comprises a semi-cylindrical head 6 from which a downwardly directed stem 'l extends; the stem being extended in a direction radial of the semi-cylindrical surface. The head 6 is adapted to seat in a liquid tight joint or seal against the upper peripheral edge of the passage connecting the cup and bottle and the stem is extended through the communicating passage 5 and is suicient in length that it will keep the valve member in proper relationship with its coacting parts whether inverted or upright.

The cap 3 of the bottle is provided on its under surface with a downwardly rounded protuberance also serves as a centering guide for the pen where ;v it is inserted'for lling. l5

3a extended into the cup, and this occupies a certain amount of space that prevents the cup beingY lled clear to the top, but will hold the level slight- 1y below the top periphery and therebyV insure against overow on insertion of a pen thereinto. The top surface of the valve head is formed Vflat, with a concentric downwardly tapered coniance, ofv the cap in preventing Vthe entirejlling of the cup when the bottle is inverted. ThisI basin used as follows: With the cap threaded'tightly onto the bottle neck, and with the parts in position, as shown in Fig. 1,'the bottle is'- inverted toV cause the valve member to drop, as shown in r Fig. 2, against the cap and permitfilling of 'the neck portion with ink. ThenV thebottle is quickly turnedf back to upright position, thereby causing ber; itbeing understood that the taper of the basin guidesthe pen point to this central location and whatever l pressure there is Vthen applied against the'valve 'will no'tcause it to tilt and'unseat. `YWith the pen thus inserted it maybeV filled in the usual way. I

7' It istobe observed in this'construction'that V `the bottleneck itself provides manning 'cup'. its restricted neck passagev providesV the valve seat and there is no complicated or expensive insert applied to the neck or bottle. The only added part ls the valve member and this, 1t is intended, shall be cast or Dressed froma relatively inexpensive material of any suitable kind.
